Supercharger

The supercharger has a self-contained oiling system that does not require a fluid change for the life of the vehicle.

However, at every 30,000 mile interval, the supercharger fluid level should be checked.
The vehicle should be parked on a level surface, the engine cool, and not running.
To check the oil, remove the Allen head plug located at the front of the supercharger. The oil level should be at the bottom of the fill plug threads when cold.
If the fluid level is low, add Synthetic Supercharger Fluid E9SZ-19577-A or equivalent meeting Ford specification ESE-M99C115
